you can also try to explain with 10million if you know.
It won't move a nudge, if you look at the trading volume in coinmarketcap, it's currently around $12 Billion. So it's just like a drop in the ocean. So that's how big the trading volume of Bitcoin as compare to the rest of crypto, it still dominates the market close to 50%.

The thing is even if whales will want to move and manipulate the market, it doesn't mean they will always make money, sometimes it could be a bad move for them to invest huge amount and then the market goes into the opposite direction.
And if some entity wants to influence the price, he has to be a big holder, like 51% of all Bitcoin in circulation. Not sure if we have that kind of statistics, but it doesn't make sense for a single whale to do that.
